Prices of materials used in the glass and glazing industry were mostly flat in June, according to Producer Price Index (PPI) data released by the Bureau of Labor Statistics (BLS).

The monthly PPI for flat glass in the commodity category was unchanged after a slight 0.2-percent decrease in May and no change in April. Those prices were up just 0.4 percent from a year ago and continue to level out on year-over-year basis.

According to the BLS, the commodity classification “organizes products and services by similarity or material composition, regardless of the industry classification of the producing establishment.”

The index for flat glass manufacturing in the industry classification was also unchanged from May, and those prices have increased 1.6 percent from June 2016.

The industry classification measures “changes in prices received for the industry’s output sold outside the industry (that is, its net output).”

Prices for fabricated structural metal products, which include glazing systems, followed their 0.6-percent increase in May with another 0.4 percent uptick in June. That index, in the commodity grouping, represents a 2.3-percent price increase year-over-year.

Ornamental and architectural metal product manufacturing, in the industry category, was up 0.1 percent for the month and 2.1 percent.

Construction input prices rose 0.2 percent in June, the sixth increase in the past seven months, according Associated Builders and Contractors analysis. However, the overall rate of increase has been slow. On a year-over-year basis, construction input prices are up 2.6 percent. Nonresidential construction input prices also rose 0.2 percent in June and are up 2.3 percent on a year-ago basis.
